The purpose of this report is to identify the various aspects of language laboratory operation and maintenance as they relate to the teacher and the administrator, and to suggest certain practices which will result in more effective utilization of the installation. Discussion of the language laboratory includes: (1) selection of personnel, (2)…

Provides a method for determining the orientation of the polar axis of an equatorially mounted optical telescope. The background theory illustrates some important properties of the celestial sphere and gives an insight into the usual "rule of thumb" methods of axis orientation; it also provides a basis for instructors and students to…

Describes a straight-forward method of measuring the absolute value of the conductance of an electrolyte solution using direct current and applying Ohm's law. (MLH)

Several teaching aids including a microcomputer system, a process control laboratory, a mechanics laboratory, and a teaching polariscope are described. (RH)

Describes a procedure which utilizes a laser beam and an interferometer to determine the stability of a holography system. Equipment set-up, operation, and interpretation of results provided. (CP)

An apparatus is described for storing laboratory glassware in freshman organic chemistry laboratories. The glassware is mounted on pegboard using hardware gripper clips, and the pegboard is fitted in a slot down one side of the storage cupboard. (BB)

Assesses the broader aspects of the roles of the physics teacher and the physicist in the Third World, and discusses some of the problems they face in general administration, teaching, and research. (GA)

Describes an experiment designed to measure the forces between charged parallel plates, and determines the relationship among the effective electrode area, the measured capacitance values, and the electrode spacing of a parallel plate capacitor. (GA)

Describes an apparatus which attempts to give a direct visual impression of the random detection of individual photons coupled with the recognition of the classical intensity distribution as a result of fairly high proton statistics. (Author/GA)

Presents several new products and equipment for teaching college science courses such as laser optics bench, portable digital thermometer, solar energy furnaces and blackboard optics kit. A description of all equipment or products, cost, and addresses of manufacturers are also included. (HM)

Describes the experiment and the apparatus used to measure electrostatic forces between charged parallel plates and points out possible pitfalls in constructing the apparatus. (GA)

A new scale is suggested, with the objective of simplifying relationships between the various scales and units used in spectroscopy. Although there are certain drawbacks to such a scale, it is hoped that the suggestion will stimulate discussion on the relevance of the many scales and units that are used. (Author/BB)

Describes a college student chemistry laboratory experiment that illustrates the construction of a polarimeter from inexpensive, readily-available materials. (HM)

Describes three pieces of scientific apparatus and their demonstrational use: a high temperature apparatus for positron annihilation studies, a digitally synthesized classroom variable star, and a demonstration of plasma laser-beam focusing using paint stripper flames. (GA)
